To all fit/"leem it only concern:

lie it known that we. t'rEPi-inn vliti. HAM- nmb and Grenen l'. llAniiLn., citizens of the 4tlnited States. residing at Canton`v countY oi" Forr'ollr. intatte ot Massachusetts, have invented :i certain newv and use'fullmproreincnt in @andy-ililrapping iiaolnnes, oi which the i'oilowing is n specification, re't'ormice heiugg had therein to the accompanying' drawigs. l

rihe preeent invention has 'for itsohect to proride n rapid and eticient machine for wrapping; individual pieces of candy in waxed or pnrclnnentized paper, the ends ot the rappers heilig twisted on each side ot the candv. and eintending'A awaiv from it, in the well low-wn manner usually employed in the inanutactnre of candy kisses.

rThe machine embodying the invention is intendeffi particularly ior wrapping glo-hulnr iliieces et hard candy. or cant j; halls, in Toppers which are cut from a wel) ot properly prepared and printed papcr. States Letters Patent. dated t ln United March l. 190i. No. 753,571. granted to Stephen M. iininhlin. there is shown and described a wrapping machine in which the wrapping paper was formed into u hori- Zontal trough iu which was deposited successively individual pieces of candy after which the paper was folded thereon and severed, the ends heilig thon twisted to torni the wrapper.

rthe machine enihodyingrv our present in.- rention 'ici-ins the wrapping'paper into vertical tnhe as distinguished from a horizontal trough and introduces the candy into the upper end oit the tube instead ot' into 'the open side ot the trough as heretofore. The (grand)7 supported in the proper posi-y tion in the tuhc hy means ot" an element which is denon'iinatcd e placer, the tuhe is then severed nt the proper point below the candy.' zitter which the severed portion of the tuhe sind the hall therein pass through the twisting instrumentalitics, and the completely wrapped piece of candy'is ejected into a suitable hopper or container.

ililhile we here described our machine in 'the present specification in the forni spe citi 'allyv adapted. for use in wrapping candy hails we contemplate its on candy cut into other shapes which approximate the spherical tiicicntlj,v to he operated upon successfully by our improved n'rachine.

The. invention will he tutti' nmlerstmid 'troni the 'following' dcscrilition taken in connection with the accompanying draw ings. and the norel tentures thereof are pointed out and clearly detined in thc claims at the ciose of this speciticzition.

The machine emhodifing our invention may for convenience or description he considered as comprising several groups of instrumentnlit-ies, as follows: (l) the feedw ing mechanism by means of which the candy halls nre supplied nt the proper intervals to` the tuhe `formed from the wrapping (3) the tuheorining und feeding mechanism; (4) thesl'iears, and. (5) the twisting mechanism,

The Candir feeding mechanism will irst lbe described: Sluiported on o. suitable lloret-liet 'l et "he right hand side ot the l f i il paper; (2) the paper supplyingl mechanism;

i table A is located a hopper' 12 having an that of the candy balls HA to be -wrapped by the machine. The lower end of the spout 13 terminates in a guide 131 adapted to direct the balls downward and is located over the point at which the tube of paper is formed so that when the spout is opened, the balls of cand may roll down one by one, being guided by the guide 131 into a cup 94 which deposits theball in the tube of paper. The balls of candy are fed singly, and at the proper 4'time 'by means ost an escapement comprising a first gate 14 and second gate 1.5.V Said first and second gates are carried on a lever 16, pivoted at 17, and operated by links 18 and 19, and an intermediate lever 20 from the main'cam lever 21 which will be hereinafter more fully described. It will be seen that when the lower end of the escapement lever 16 is depressed, the irst gate 14 closes the end of the spout but the second gate 15 is out of the path of the candy balls so that the row of balls rests against the first gate 14. lVhen the escapevment lever 16 is moved into its opposite position the firstgate 14 is moved out of the path of the balls, allowing the bottom ball to escape, while the second gate 15 holds back the other candy balls. The escapement is so timed by connection with the -cam lever 21 that a single ball is delivered to the cup 94 which descends and deposits the ball in the open end of the tube of wrapping paper after the tube has been formed and raised into position.

The paper feeding mechanism will now be A described. A roll or web 22 of suitable Wrapping paper` is supported in a bracket 231. From this roll 22 the web of wrapping paper 23 is led oil'. It passes first through a pair of guide rolls 24 then througha pair of snubbing rolls 25 and 26, one of fvvhich is preferably constructed of rubber so that a tension may be placed on the paper to prevent Atoovrapid movement of the paper. The paper is drawn from the roll 22 by means of a striker roll 27 mounted on a bracket 23 which is itself carried on the vertically reciprocating. cross head 30 on which the grippers, which will be hereinafter fully described, are also carried. Since the snubbing rolls 25 and 2G hold the strip of paper quite firmly, the downward movement of the striker roll' 27 unwinds a certain amount of paper from the roll 22 every time that the striker roll descends. By this means an even supply of paper is lprovided without placing undue strain on it.

y The tube forming mechanism will now be described: After passing through the snubbing rolls 25 and 26 the paper passes about a guide roll 31 and thence upwardly up through helical feeding tube 32 by means of which and of certain other instrumentalities the paper is converted into a tube or cylinder oi a diameter about e ual to that of the candy ball to be wrappe The paper is guided to the helical feeding tube 32 by means of a wire loop (see Figs. 1, 2 and 13) which begins the work of convertingr the flat paper into a tube, and then through a giude (see Fig. 12) consisting of a horse-shoe shaped wire loop 34. In Figs. 12, 13A and 14 the paper is indicated by the dash lines 23. Said wire loop 33 and upper wire loop 34 are supported on a bracket 3G depending from the under side of the table A. rl`he helical feeding tube 32 is flared slightly to `facilitate the formation of the tube and its construction will be fully understood from an examination of Fig. 14 in which the feeding tube is shown in section. From this figure it will be seen that the paper comprising the tube is lapped for a distance of about equal to the diameter of the ball to be wrapped.

The paper tube thus formed is intermittently fed upwardly by means of three grippers, one ovwhich 37 (see Figs. 1, 4, and 5) is located within the-tube and the others of which, 38 and 39, are located outside the tube. The proximate faces of the three 'grippers are slightly serrated or knurled so that they may get a better grip upon the paper. The outside grippers 38 and 39 are fulcrumed at 40 and 41, respectively, to the cross-head 30 and extend below the said fulcrulns 40 and 41, being engaged at their lower ends by means of a toggle joint composed of links 42 and 43, pivoted at 44. The opening and 'closing of the grippers at the proper times is accomplished by giving to the central pivot 44 of the toggle joint a greater or less upward or downward movement, as the case may be, than the movement of the lower ends of the outside grippers 38 and 39, so that the toggle joint is brought into action.

The cycle of movement of the grippers starting with them in the position which they are in..Fig. 4 is as follows: First the grippers close upon the tube (see Fig. 5) then they move down carrying it with them for a short distance to smooth 'out the end of the tube which may have beencrushed by the previous action of the severing mechanism; then they move up to the top of ltheir stroke carrying the tube of paper with them here they open and release the tube; and inally they move down to the position shown in Fig. 4. The closing of the grippers on the tube oi". paper is accomplished by causing the main cam lever 21 to descend suddenly by dropping into an indentation L15in the cam E, while secondary cam lever 46 which is pivoted at 47 to the main cam lever still rests on the periphery of aseoo'udary cam 48 which is secured to the main Cfr.

Y l it As previously described the balls of candy are dropped one by one into the cup 9-1 which descends into the ope-n end 'of the paper tube and deposits the ball on the ripper end of the placer 60 which is a. finger or continuation on the placer rod :37. The parts are so timed that the central gripper is at the top of its movement at the moment when the ball drops out of the spout into the cup. As will be seen from Fig. l, the tube extends above the ball on t-he placer 60 o distance vsufficient to form the twist on the inished candy wrapper. When the candy ball is in place in the tube it is supported on the lower side, as previously stated, upon the -Y upper end of the placer 60 and on the right hand side by :i spoon-finger 61 which is composed of thin mbtal hollowed out to form a slight depression in which the curve of the candy ball rests. y

The next step in the circle of movements i of the machine is the 'severing of the tube of paper at' the proper point below the candy ball. Before this can take plut-e however it is necessary for the ball and'tube to be held in the position just described and the placer removed. The candy bull and tube are held in place by means of a spring l against the spoon-finger Gl. As the disk 62 carried on a rotating disk 63 which caru ries a. 'moving twister by vmeans of which the ends 'of vthe wrapper are twisted. The disk 63` is supported on the upper end of u shaft 6ft driven by the spiral gears F and Y G. The spring 62 is slotted as seen at-.641

Fig. l and is secured at one end to the disk and at the other end is guided bymeans of a .link 65 pivoted at one end to the disk 63. By this mel-ens the spring 62 is free to yield somewhat so that it may hold the candy bell with a substantially uniform pressure rotates the candy bail engaged by the edges of the slot 6451 in the spring @32 and held firmly so that neither it nor the paper tube can be 'moved vertically by the downward movement of the interior gripper 37 and plecer as theplecer 60 is withdrawn from below Vthe Candy bell. The paper tube is their severed the' proper distance below the cendy bell by means of shears composed by bled@ '67 and 68 pivoted ut 6.9., end operated by a toggle joint 70. Seid toggle" joint is operated by a' wiper cam 7l.' ectingcn the cam lever 755; seid wiper com, isrevolved bysuiteble gearing 73 driven by the sheft 64- which also rota-tes the twist- 'ing mechanism. s. frs the -action of the shearsupon ,the 'tube tends to force the'tube Atoward their points slightly, and. es there is nothing to prevent the tube of paper unrolling as the cutting taires place we provide' a. pair of movebie hogere 74 pivoted 4at 75 and held against the 'tube by the spring 76. The iingers 7.5.: are moved ontot'the wiy (LTI of the tube of peper when it is moved` up into position the disk 63.

' The mechanism by means of which the ends of the tube of paper are twisted will now be described. The further rotation of theV disk 63 releases the ball from the slotted spring G2 and it is then caught between the twisters which comprise a movable member 77 on the disk 63 and a fixed member 78 which is supported on the frame of the ma chine. The fixed member is provided with top and bottom plates 79 und 80 (sce Fig. 10) which project toward the disk (53 and are curved to correspond in shape with the periphery ofrthe disk 63. Between the top and bottom plates 79 und S0 is located u, curved rubber surface 8l against which the ball lies. The twister 77 on the disk 63 is composed of corresponding parts, und has top and bottom plates 82 and 83 and n. rubber surfiice 84: so that the ball is held between the two rubber surfaces 81 and 84. The t'wo top plates und the two bottom plates are separated from each other by u space which is slightly greater than the thickness of the folds of thc wrapper after -it has been twisted. The movable gripper on the disk G3 is adjustable toward and awayfrom the stationary4 gripper by means of cep screws 85 located in slots 8G. It' will be seen that as the disk 63 revolves the ball-is caught between the two rubber' surfaces 81 and 8st and caused to revolve, as the rubber surface Sl is stationary while the rubber surface 84 travels past it. Sii ce ythe ends of the 'wrapper extend npwardiy and downwardly in the spaces between the. pair of top plates and the pair of bot-toni plates they cannot turn but slide in this space and it results that the ball is twisted relatively by means of projection 901 on vto the ends of the wrapper and the twists ure in the same direction. The lingers 74 are also moved out of the way when thetwisting takes place by means of the guide 87 (see Fig. 9) carried on the niovlng twister. The fixed twister 1s spring-pressed against the moving twister, being carried on guide pins 88 and 89 and outwardly pressed` by springs 90 and 91. The motion of the said fixed twister toward the movable twister is limited by means of the bolt 92'.'

lThis arrangement compensates fully for tube feeding mechanism. forms the tube drawing the peper from the roll and oper etes to feed upwardly e length of tube sufficient to wrap one bull of candy for the twisted ends of the. wrapper; a single ball drops from the delivery tube of the hopper intolthe. cup which descends und leaves the ball supported on the placer and properly positioned inside the tube of paper. rl`he ball is then ser/:ed between a spring on the twister and the spoon shaped finger and the placer is withdrawn. A finger' holds the paper tube in shape while the shears are severing the tube at the proper point. The ball is'then caught betweenthe moving and lixedtwisters and as the moving twister passes the .fixed twister the ball is rolled along between the two completely twisting the wrapper at each end and as the movabletwister passes beyond the fixed twister the wrapped ball is dropped clear of the machine; The grippers which feed the'tube upwardly t-hen operate to pull the crushed end of the tube, which. results from the severing operation downwardly over the edge of the cup thus restoring the tube to its smooth cylindrical'form preparatory to thenext upward feed movement.

This immediately takes' place and the operafl tions heretofore described are'repeated.v

What we claim is l. In a candy wrapping machine, the combination of tube forming mechanism, anda placer extending upwardly into the tube of paper to support the piece of candy to be wrapped in proper position within the tube of paper formed by the tube .forming mechanism. l

Q. In a candy wrapping machine, the eombination with tube-forming 4mechanism and a placer extending upwardly into the tube of paper to support the picco of candy to be wrapped, in proper position within the tube of paper, with interior and exterior grippers and means to reciprocate said grippers vertically and to open and close' said grippers upon the tube of "paper to feed the tube relatively to the placer.

2. ln a candy wrappingmacl'iine, the com bination with tube forming mechanism, and a placer extending upwardly into the tulle of papel.' to support the piece ot' candy to hc wrapped in proper position within the tube of paper formed by the tube-forming mechanism, and a pair of tubular guides one iuY side the other to guide the paper vertically. said interior tubular guide being flared slightly at its outside edge to straighten the tube of paper when it has becol'ne crushed.

4. ln a candy \\'ra1`)ping nulchinctlu=l combination with tube forming n'u .cl1anisui, feeding n'lechauism for the tube forrmd thereby, and holding mechanism to support the tube and a piece of candy therein, while the tube feeding mechanism is moved out; of position, comprising a spoon finger and a rotating slotted spring, said spoon linger engaging the piece of candy on one side and the slotted spring engaging the piece of candy on the other side.

In a machine of the character described, the improved wrapper twisting ueehanism. comprising a fixed twisting member and a moving twisting meu'ibcr, both of said twisting members being provided with to'p and bottom plates of co1'respondingl shape between the proximate edges of which is a spa-ce through which the ends of the wrappers project, both Yof said twisting members being also provided with resilient portions located between said top and bottom plates, said resilientportions contacting with `the portion of the wrapper over the piece of candy 'being wrapped 'whereby the central portion of the wrapper containing the candy is rotated while the ends are held from rotating between the pair of top and bottom plates.

G. ln a machine of the character delscribed, the improved wra per twistinrr mechanism comprising a ixed twisting member and a rotating twisting member, both of said twisting members being provided with top and bottom plates of .corres .spending shape between the proximate edges scribed, tube forming mechanism, a verti cally reciprocating cup located within the tube of paper formed by the tube forming mechanism and candy feeding mechanism adapt ed to deliver the pieces ot' candy one by one into the said cup.
